Abstract

A method for measuring nucleic acid amplification in real time which uses a real time Polymerase Chain Reaction (PCR) instrument with capillary tubes as reaction vessels, is new. A fluorescent dye is added to the reaction mixture and remains unchanged throughout the reaction. The capillaries are adjusted to the position where the fluorescence has a maximum value and fluorescence emission is carried out during and optionally after the reaction. Independent claims are also included for: (A) a system comprising a real time PCR instrument with several capillary tubes as reaction vessels, a reaction mixture comprising a thermostable polymerase, deoxynucleotide, buffer and a fluorescent dye which remains unchanged throughout the reaction; (B) a reaction mixture comprising a thermostable polymerase, deoxynucleotide, buffer and a fluorescent dye with an emission wavelength of at least 600nm which remains unchanged throughout the reaction; and (C) a kit comprising the reaction mixture.
